When it comes time to mount your favorite Leupold scope on your favorite rifle why not use original Leupold Quick Release scope rings. Designed to mount specifically to Leupold quick release bases (sold separately) these forged and machined scope rings allow you to mount a scope, zero it, remove the scope and upon reattaching the scope you will remain nearly dead on with your original zero. To install these rings simple turn the lever forward to engage the base, then pull the ring down and forward locking it into position. Don't get stuck using some other brand, stick with Leupold for all your optics and optics mounting needs.
